(Cl. iS-145)v 4 Claims.

This invention relates to safety devices for firearms.

The principal object of the invention resides in the provision of an extremely easily operable device for holding a breech bolt of a firearm in open condition, so that the-firearm may notbe accidentally fired.

A further object of the invention resides in the i provision of a rearm having a pivoted hook or the like which is movable into the path ofan action bar so as to engage the latter at its rearwardrnost position, to hold-the action bar in said rearwardmost position, said hook being moved 'into the path of the action bar by means of a spring, and there being provided 'a hand operated:

member to engage the noch and hold the same out of the path of theaction bar against the Vaction of theV spring; and the yprovision of a device as above described including a connecting lever between the firearm Sear and the action' bar, said connecting lever being engaged by the A still further object of the invention resides in the provisionv of a firearm having a reciprocating breech bolt, an action bar connected thereto for movement therewith, and a pivoted hook in position to engage the action bar atthe rearwardmost point of its travel and latch the same to hold the breech bolt open, said hook having acam-shaped nose so that when the hook is'A positioned in the .path of the. action bar,` the latter is enabled to'ride over the hook and become latched upon manual retraction of the action bar.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is a longitudinal sectional view through the receiver of a firearm provided with a safety device of the present invention, parts being broken away;

Fig. 2 is a View in elevation of the receiver of a rearm according to the present invention showing the firearm in firing condition, parts being broken away;

Fig. 3 is a view similar to Fig. 2 but showing the firearm in safe condition;

Fig. 4 is a view in elevation of the safety hook; and

Fig. 5 is a top plan view of the same.

In the presentV invention, there is presenteda relativelyA simple but extremelyr positive safety device for use in firearms having a reciprocating action bar, oner example of which is disclosed in the present case and which is also shown in copending application-No.- 494,660, filed July 14, 1943, now abandoned, and also in Patent No. 2,422,854, July 1, 1947. There are, of course, other rearms to which the present invention may be applied'.

In Fig. 1, there is shown a firearm having a barrel IB, a receiverV l2, a breech bolt chamber I4, and a reciprocating bolt i6 therein having a firing-pin i8.' In the particular illustration herein, the breech bolt chamber is provided with a reciprocating-hammer 2B having a hammer spring 22v located at one end against a' bumper plug 24 closing the chamber I4;

Asv will be well recognized, the bolt I6, which is shown in breech closed condition in Fig. 1, re'ciproca'tesV in the chamber I4 and since itvcarries the ring pin I8 therewith, the iirearm cannot be operated unless'the breech bolt-is in breech closed condition.

An action bar 26, which is spring pressed forwardly to breech bolt closedl condition by-a spring 28, is connected to the bolt I6'by means of a rear plate 3U, which is-engaged' in the bolt as, for instance, by a slot at 32. The action bar 26 slides in a guide formedby studs 31B and a magazine plate 36 for a magazine holder 38.

A trigger block is shown at 40' pivotally-mounting a trigger 42 having a spring 44. Pivoted to the trigger at 46 is a connecting lever 'havng a spring 50 urging the connecting'lever into the path of the action bar. Lever 48 is provided with a shoulder 52 adapted to engage a corresponding shoulder on a sear 51%, the sear engaging the hammer 2D and holding the same in the Fig. l position until the trigger is pulled, moving the lever 48 forwardly and pivoting with it the scar so as to withdraw the same from the hammer to allow the latter to move forwardly under action of the hammer spring to actuate the ring pin. It will be, of course, obvious that when the bolt retracts, the action bar will depress the lever 48 and allow the sear to return to its active position under iniiuence of the sear spring which is indicated at 56. As so far described, the firing mechanism of the firearm follows the mechanism described in the above noted pending application and patent.

A lever 58 is pivoted at 59 on the trigger block 40 and is provided with a spring in the trigger block indicated at 60, see Figs. 2 and 3, said spring pivoted at 66 on the trigger block 40 and having l an inturned flange 68 in position' to engage the underside of the projection 62 and forcibly press the hook lever 58 downwardly to the Fig. 1 position when lever 65 is pivoted to the Fig. 2 position so as to retract the hookY 64 out of the path of the action bar 26, thus providing for continued firing of the rearm.

When, however, the lever 65 is moved to the Fig. 3 position, the flange 68 moves out of contact with projection 62 and thereby allows the spring 60 to come into play to resiliently urge the hook lever 58 upwardly to the Fig. 3 position so as to catch the action bar upon rearward movement thereof.

The connecting lever 48 is provided with a stud 10 which is engaged by the flange 68 to depress lever 48 at the same time that the hook lever is allowed to rise thus providing for a double safety feature disconnecting the sear from the trigger, and thus insuring that the ring pin cannot be actuated under any circumstances.

The free end of the hook lever 58 is provided with a cam nose 'l2 so that the action bar can ride over the hook 64, the spring 6U causing the hook to rise behind the action bar plate 30 to latch the action bar at any time when lever 65 is on safe position, as shown in Fig. 3.

It will be seen that this invention presents a simple and yet extremely effective safety device which holds/the breech bolt in open condition as is usually required to indicate that the gun is safe. At the same time, the connecting lever 48 is also immobilized so that the lever 65 produces a double safety feature.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is:

1. Safety device for a rearm having a recip- `rocable action bar and connected breech bolt comprising movable means in the path of the action bar for selective engagement therewith to hold the same and the bolt in breech open condition, a sear, means to positively move the said movable means out of the path of the action bar to provide for normal function thereof, and a connecting lever between the action bar and sear, said means disengaging the lever from the action bar.

2. Safety device for a firearm having a reciprocating breech bolt and connected action bar, a hammer, a sear, and a connecting lever between the action bar and sear, comprising a movable means selectively movable into or out of the path of the bar, means on the movable means to engage and stop the action bar when the latter is in the action bar path, and hand operated means to move the movable means, said hand operated means engaging and disconnecting the connecting lever from the sear.

3. Safety device for a firearm having a reciprocating breech bolt and connected action bar, a hammer, a sear, and a connecting lever between the action bar and Sear, comprising a movable means selectively movable into or out of the path of the bar, means on the movable means to engage and stop the action bar when the latter is in the action bar path, resilient means moving the movable means into the action bar path, hand operated means to engage the movable means and retract the same from the action bar path against the action of the resilient means, said hand operated means engaging and moving the connecting lever out of connection with the sear upon actuation of the hand operated means to release the movable means to permit the resilient means to move the movable means into the action bar path.

4. Safety device for firearms comprising a reciprocating breech bolt, an action bar connected thereto, a hammer, a sear, a connecting lever between the sear and the action bar, the latter depressing the lever and disconnecting the sear during rearward motion of the action bar, a pivoted hookto engage and latch the action bar in the rearwardmost position of the latter, a spring urging the hook into the action bar path, and a hand operated element to engage and retract the hook from the action bar path against the action of the spring, said element engaging and disengaging the connecting lever from engagement with the sear upon actuation to release the hook.
